Description

Technical Field

[0001] The invention relates to the technical field of water resource regulation, and in particular to a coupled drainage system. Background Art

[0002] Water storage tanks are a common type of storage facility, often used in water supply, water treatment, water supply and other systems. In order to meet the basic functional requirements and ensure safe and effective operation, water storage tanks must have normal drainage functions. If the drainage system is not set up properly, it will affect the functional effect of the water storage tank, and in serious cases, health and safety accidents may occur. At present, the drainage system of the water storage tank only considers overflow drainage and emptying drainage, and there is no roof drainage, which makes the water on the roof in an unorganized drainage state; overflow drainage is achieved by hoisting the overflow drainage pipe at a predetermined height below the roof of the water storage tank to achieve the drainage effect. The overflow drainage pipe needs to be installed after the construction of the roof of the water storage tank is completed, and the overflow drainage pipe is close to the roof, which makes the construction difficult; and the overflow drainage pipe is fixed with a hanger. After long-term operation, the hanger is prone to corrosion, reducing the structural safety and equipment stability; because the roof drainage is not considered, the rainwater and flushing water on the roof are all unorganized drainage, which is easy to produce water stains on the outer wall of the tank body, and the roof is waterlogged, which affects the appearance, poor operation and maintenance conditions, and increases the operation cost and maintenance workload of the water storage tank.

[0031] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0033] like Figure 6-7 As shown in FIG. 1 , the drainage system of the existing water tank 1 only considers overflow drainage and emptying drainage, and the drainage at the top of the water tank 1 is unorganized free drainage; the overflow drainage is achieved by installing an overflow pipe near the top of the water tank 1, and the overflow pipe is fixedly installed on the top wall of the water tank 1 by a hanger 7, and the other end of the overflow pipe extends outward from the water tank 1 and leads the overflow water to the nearby drainage system. The elevation of the overflow pipe outlet is the designed overflow water level, and the overflow pipe outside the water tank 1 extends from top to bottom along the outer wall of the water tank 1 to below the ground, and is buried below the ground and led to the auxiliary drainage system; since the overflow drainage needs to be stored again The overflow pipe can be installed only after the top plate of the water tank 1 is constructed. The outlet of the overflow pipe is close to the top plate, and the construction process of the whole process is relatively complicated and difficult. Moreover, the overflow pipe is hoisted on the top plate by a hanger 7. After long-term operation, the crane is prone to corrosion, resulting in reduced structural stability and poor safety and reliability. Moreover, the overflow pipe is arranged along the outer wall of the water tank 1, affecting the overall aesthetics of the water tank 1. In addition, the top drainage of the water tank 1 is not taken into consideration, resulting in unorganized drainage of rainwater and flushing water on the top plate, which is easy to leave water stains on the outer wall of the water tank 1, or accumulate water on the top of the water tank 1, which is not conducive to subsequent operation and maintenance.

[0034] like Figure 1-Figure 5As shown, the embodiment of the present application proposes a coupled drainage system, including a water storage tank 1, the water storage tank 1 has a tank cavity 11 for storing water, the tank cavity 11 is respectively connected to a water inlet pipe 2 (supplying water into the tank cavity 11) and a water outlet pipe 3 (supplying water to users); an overflow well 4 is arranged in the tank cavity 11, the overflow well 4 extends upward from the bottom wall of the tank cavity 11, the top of the overflow well 4 is spaced from the top wall of the tank cavity 11, the top of the overflow well 4 has an overflow port 41 connected to the tank cavity 11 and the overflow port 41, and the overflow port 41 is connected to the tank cavity 11 and the overflow port 41. 1 is the designed overflow water level (when the water level in the pool cavity 11 exceeds the designed overflow water level, the excess water is poured into the overflow well 4 through the overflow port 41), the bottom of the overflow well 4 is connected to an overflow drainage pipe 42 extending outward from the pool cavity 11, and the water poured into the overflow well 4 is discharged outward to the nearby drainage system through the overflow drainage pipe 42. The overflow well 4 in this solution can be constructed simultaneously with the water storage tank 1, and there is no need to wait until the construction of the water storage tank 1 is completed before construction, which effectively shortens the construction period; Figure 2 As shown, part of the bottom wall of the pool cavity 11 is concave downward to form a water collection pit 12, and the water collection pit 12 is connected to an emptying drain pipe 121 extending outward from the pool cavity 11. An emptying valve is provided at one end of the emptying drain pipe 121 extending outward. When the water in the water storage tank 1 needs to be emptied, the emptying valve is opened to empty the water in the water storage tank 1. When it is not necessary to empty, the emptying valve is in a closed state; Figure 4 As shown, a drainage hole 13 is provided through the top of the water tank 1, and a top plate drainage pipe 131 connected to the bottom of the drainage hole 13 is provided in the tank cavity 11, and the other end of the top plate drainage pipe 131 extends outward from the water tank 1, so that rainwater or flushing water on the top of the water tank 1 enters into the top plate drainage pipe 131 through the drainage hole 13, and is discharged outward through the top plate drainage pipe 131, so that the originally unorganized top drainage is transformed into organized drainage.

[0035] In the specific implementation of this embodiment, when the water level in the pool cavity 11 exceeds the designed overflow water level, the excess water is poured into the overflow well 4 through the overflow port 41 and discharged outwardly to the drainage system of the accessories through the overflow drainage pipe 42 at the bottom, thereby realizing the overflow drainage of the water storage tank 1. The overflow well 4 in this embodiment does not require any fixing measures, so that the stability of the later operation of the water storage tank 1 is improved. At the same time, since the overflow well 4 is arranged inside the water storage tank 1, the traditional arrangement close to the outer wall of the water storage tank 1 is avoided, which leads to a decrease in aesthetics; When it is necessary to flush the top of the water tank 1 or when natural rainfall occurs, the flushing water and rainwater enter the top plate drainage pipe 131 through the drainage hole 13 provided on the top of the water tank 1, and are discharged outward through the top plate drainage pipe 131, so that the originally unorganized top drainage is transformed into organized drainage, which effectively avoids the situation where water stains are easily generated on the outer wall of the water tank 1. At the same time, since the top drainage pipe is arranged in the tank cavity 11, compared with the arrangement outside the water tank 1, it not only enhances the aesthetics, but also reduces the impact of open-air environments such as sunlight exposure on the service life of the pipeline.

[0036] In some embodiments of the present application, Figure 1 , Figure 4 As shown, the projection of the drainage hole 13 in the up-down direction is located within the projection range of the overflow well 4 in the up-down direction, and the top plate drainage pipe 131 includes a first pipe 1311 extending up and down, and a second pipe 1312 connected to the lower end of the first pipe 1311; the first pipe 1311 is located in the overflow well 4, and the lower end of the first pipe 1311 extends downward to the bottom of the overflow well 4, and the second pipe 1312 extends in the horizontal direction, and the other end of the second pipe 1312 extends outward from the water storage tank 1.

[0037] In this embodiment, the first pipe 1311 connected to the drainage hole 13 is arranged in the overflow well 4. On the one hand, it can realize the discharge of rainwater or flushing water on the top of the water storage tank 1. On the other hand, since the interior of the overflow well 4 is basically in a water-free state, the first pipe 1311 is prevented from being immersed in water for a long time, effectively extending the service life of the pipe; the rainwater or flushing water flows through the first pipe 1311 and the second pipe 1312 in turn, and is finally discharged to the outside, thereby avoiding secondary pollution to the medium in the water storage tank 1.

[0038] In some embodiments of the present application, Figure 4 , Figure 5As shown, a slope 14 is provided at the top of the water tank 1, and the slope 14 is inclined from top to bottom toward the drainage hole 13, and the bottom end of the slope 14 extends to the upper end surface of the hole wall of the drainage hole 13. The setting of the slope 14 can make the rainwater or flushing water on the top of the water tank 1 enter the drainage hole 13 more easily, improve the drainage efficiency of the rainwater or flushing water on the top of the water tank 1 (so that the rainwater or flushing water on the top of the water tank 1 is discharged outward in an organized manner through the drainage hole 13 as much as possible), and avoid the situation where the rainwater or flushing water on the top of the water tank 1 is discharged unorganized along the outer wall of the water tank 1.

[0039] In some embodiments of the present application, Figure 4 As shown, a cofferdam 15 extending upward is provided on the top of the water tank 1. The cofferdam 15 is arranged around the top edge of the water tank 1, and the height of the cofferdam 15 is about 100 mm to 150 mm. The arrangement of the cofferdam 15 effectively prevents rainwater or flushing water on the top of the water tank 1 from being discharged along the outer wall of the water tank 1.

[0040] In some embodiments of the present application, Figure 5 As shown, a filter screen 16 is provided in the drainage hole 13 for filtering debris such as leaves.

[0041] In some embodiments of the present application, Figure 1 As shown, the overflow well 4 includes a first overflow plate 43 and a second overflow plate 44 extending up and down, the upper ends of the first overflow plate 43 and the second overflow plate 44 are spaced from the top wall of the pool cavity 11, and the height of the first overflow plate 43 and the second overflow plate 44 is the designed overflow water level height; one end of the first overflow plate 43 in the horizontal direction is vertically connected to one end of the second overflow plate 44 in the horizontal direction, and the other ends of the first overflow plate 43 and the second overflow plate 44 are respectively connected to the side wall of the water storage tank 1 to form the overflow well 4. In order to ensure the overflow drainage capacity, the sum of the length of the first overflow plate 43 projected in the up and down direction and the length of the second overflow plate 44 projected in the up and down direction in this scheme is not less than 6 times the square of the diameter of the water inlet pipe 2, and not less than 2m; the diameter of the overflow drainage pipe 42 is not less than 1.25 times the diameter of the water inlet pipe 2.

[0042] In some embodiments of the present application, the coupled drainage system further includes a collecting drainage well 5, and the overflow drainage pipe 42, the emptying drainage pipe 121, and the second pipe 1312 are all connected to the collecting drainage well 5; the collecting drainage well 5 is provided with a collecting drainage pipe 51 connected to the outside. The flow capacity of the collecting drainage pipe 51 needs to consider the larger value of the sum of the top plate drainage and the emptying drainage, and the sum of the top plate drainage and the overflow drainage, and the area of ​​the flow cross section of the collecting drainage pipe 51 is not less than 1.1 times the sum of the area of ​​the top plate drainage pipe 131 and the emptying drainage pipe 121 (or the overflow drainage pipe 42); in this embodiment, the collecting drainage well 5 is provided (the emptying valve on the emptying drainage pipe 121 is provided in the collecting drainage well 5, and the collecting drainage well 5 also serves as a valve well to reduce static investment), which is conducive to the centralized management of drainage system facilities.

[0043] In some embodiments of the present application, Figure 4 As shown, a buffer section 1313 is provided at one end of the first pipe 1311 close to the drain hole 13, which is used to buffer the rainwater or flushing water on the top of the water tank 1 to a certain extent.

[0044] In some embodiments of the present application, the slope of the slope 14 is not less than 3‰.

[0045] In some embodiments of the present application, Figure 1 As shown, an inspection port 17 is provided at the edge of the top of the water tank 1, and an inspection ladder 6 corresponding to the inspection port 17 is provided on the inner wall of the tank cavity 11, so as to facilitate the staff to inspect and maintain the inside of the water tank 1 in the later stage; at the same time, an inspection port 17 is also provided on the top of the water tank 1 above the overflow well 4, and an inspection ladder 6 is provided in the overflow well 4, so as to facilitate the staff to inspect and maintain the inside of the overflow well 4.

[0046] In summary, the embodiment of the present invention provides a coupled drainage system, which optimizes and improves the existing drainage of the water tank 1, and sets up a new overflow drainage and top plate drainage. The newly designed overflow well 4 effectively improves the safety and reliability of the operation of the drainage facilities; at the same time, the organized top plate drainage allows rainwater and flushing water on the top of the water tank 1 to be discharged in time, avoiding the traditional unorganized drainage that causes water accumulation on the top of the water tank 1 and water stains on the outer wall of the water tank 1, providing convenience for the maintenance of the water tank 1 in the later operation, and reducing the cost and maintenance workload of the operation and maintenance of the water tank 1; in this solution, the top plate drainage pipe 131 is located in the overflow well 4 to avoid long-term immersion in water, effectively extending the service life of the top plate drainage pipe 131. Compared with being arranged outside the water tank 1, it not only enhances the aesthetics, but also reduces the impact of open-air environments such as sunlight exposure on the life of the pipe.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
